T 0 all wit-0m it may concern:

Be it known that I, PHILIP N. HANSEN, a citizen of the United States, and resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Opticians Finger-Piece- Mounting Pliers, of which the following is a specification.

An object of this invention is to provide a pair of pliers so constructed that the optician may perform all the operations necessary for the alignment of finger piece mountings and the adjustments of the guards. This I have effected by constructing a pair of pliers, the jaws of which are elongate semi-cones, having internally flat faces and being externally reduced forwardly from heel to tip so that when the two jaws are brought together they substantially form a conical projection; and I provide the fiat inner faces of the forwardly reduced jaws with opposed concavities all of which and the purpose of which will be shown in the accompanying drawing and more fully pointed out in the subjoined detail description and the appended claims.

Other objects, and features of invention may appear from the 'accompanyingdrawing, the subjoined detail description and the appended claims.

The accompanying drawing illustrates the invention in the form to which I have reduced the same into practical use.

Figure 1 shows the invention in position for use in a pair of glasses which are shown as being held firmly by the pliers applied to the guard screw that is engaged top and bottom within the countersinks or sockets of the pliers.

Fig. 2 shows the meeting faces of the pliers separated and laid side by side.

Fig. 3 is a fragmental view of the pliers open, showing one of the sockets.

Fig. 4 1s an enlarged fragmental view of the pliers in position for use and illustrating the screw-grasping feature.

Fig. 5 is an enlarged fragmental view of the pliers partly in section showing the location and articulation of the sockets.

Fig. 6 is an enlarged fragmental axial section of the jaws set on a lens screw to hold the same firmly.

Fig. 7 is a side view of the pliers closed showing the snipe nose character of the pliers.

Fig. 8 is a cross-section on plane indicated by line 00 Fig. 5 and on the scale of Fig. 5.

The pliers terminate in an elongate split cone forming two semi-conical jaws 1, 2, which are provided with like fiat inner juxtaposed faces 3, 4; making practical contact with each other throughout their full length. Near the free ends or points 5 of the jaws on inner faces 3, 4; there are provided concavities, countersinks or sockets 6, directly opposite each other when the jaws are closed; said concavities being spheroidal in form and calculated to hold securely the ends of the guard screw or any like screw or pin that they may engage' By providing the sockets 6 in the juxtaposed fiat faces of the elongate semi-conical jaws, the instrument is adapted for holding the guard pin; and the instrument may be inserted into limited spaces and the forwardly converging sharp edges 8 are adapted to grip objects from tip to heel of the jaws.

In practical use the Optician will grasp the tool by the handle and will operate the same in accordance with the requirements and is not required to lay down and pick up the pliers with the frequency heretofore required with the pliers heretofore known.

The edges 8 of the two jaws conform to each other when the jaws are closed and are therefore adapted to take hold, as desired upon the screw by the ends, when the screw is seated, or to take hold of it for the purpose of inserting it in the strap of the spectacles. The operator may therefore greatly expedite his. work.

The pliers may be handled in practically the same way as ordinary snipe nose pliers wherever that kind of pliers would be adapted for use. When it is desired. to adjust a finger piece mounting, and for the alignment of same, which is the screw plier feature and snipe nose feature combined.

Oftentimes it happens when wearers have accidentally or otherwise bent their glasses, that with the simple snipe nose plier form shown it is impossible to adjust the bridge and put it back in its former position for the reason that it slips; and to put the glasses in their former position there is only one point of the bridge that the Optician can take hold of or set these newly invented pliers to properly straighten glasses to their true position; and that is to place the pliers on the guard screw and make adjustment 2. A pair of opticians pliershaving half round tapering jaws Which unitedly form a split cone, andeach jaw having a semispheroid concavity one of Which cavities is directly opposite the other.

In testimony whereof, I have hereunto set my hand at Los Angeles, California this 21st day of'May, 1920. Y

PHILIP N. HANSEN.
